RADIATOR ATTACHMENT.

Application filed January 20, 1925. Serial'No. 3,7071.

To all 107mm t may concern.'

Be 1t known that I, ALFRED L. Soriana citizen of the United States, residing at. Chicago, inthe county of @ook and Statey of Illinois, have invented certain new and useful Improvements in Radiator Attachments, of which the following is a specilication. p

This invention relates to radiator attachments for motor vehicles and more particularly to a device for securing radiator ornaments, signal devices and the like to automobile radiators to preventtheir unauthorfilling spout of a radiator to prevent removal of the signal or the like, common means being employed for actuating the gripping members.

A still further object is tol provide gripping means for securing the device in place on the radiator in such manner as to prevent loss of water or water vapor from the radiator.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the drawings I have shown one embodiment of the invention. In this showing- Figure 1 is a central vertical sectional view showing the device in place on a radiator, parts being shown in elevation,

Figure 2 is a horizontal sectional view through the device, and, Y

Figure 3 is a detail perspective view of the gripping members and operating means therefor.

Referring to the drawings the numeral 10 designates an attachment mounted adjacent the filling spout of an automobile radiator and shown in the present instance as a signal provided with a movable cap 11 adapted to be actuated by fluid pressure created in the v radiator under' abnormal conditions to serve as a warning to the operator. rlhe' signal l0 is adaptedto be mounted over the usual radiator l2 having a filling spout' 13 which is threaded as at 14 for connection with the usualcap employed.

The present invention includes a base designated as a whole by the reference numeral 15 adapted to be arranged o-ver the spout of the radiator. The base 15 may be suitably hingedas at 16 to the signal 1() at one side and may be provided at its opposite side with locking means 17 of any desired type to maintain the signal in closed position as shown in Figure 1. The member 15 is provided in its upper face with anV annularV groove 18 in which is arranged a packing ring 19 preferably formed of rubber and adapted to be engaged by a flange 20 projecting from the bottom of the signal. The engagement of the flange 2O` with the packing 19 is adapted to form an air-tight joint between the signal and the base 15. i v

The base member 15 comprises a pair of spaced substantially annular walls 21 and 22 providing therebetweena circular space 23 of substantial width. Itwill be obvious that the space 23 is adapted to receive radiator yspouts 13 of varying diameters threaded Qi'ther externally or internally. A washer or packing ring 24 is arranged in the upper end of the space 23 and is adapted to engage against the upper end of the lilling spout as shown. in Figure l. A spring washer 25 is provided for maintaining a leak-proof Contact between the ring 24 and the filling spout to prevent loss of water or water vapor from the radiator. The inner wall 22V is provided at spaced points with thickened portions `or lugs 26 as shown in Figures 1 and 2 and these lugs are connected at their i lower ends by a spider 27. The spider is provided with a central upstanding bearing 28 having a central aperture 29 adapted'to rotatably receiveY a vertical pin 30. The upper end of the pin 30 is provided with a plurality of preferably integral cams 31, one

of which is provided in one face with ratchet teeth 32 as clearly shown in `Figures 2 and 3. The pin 30 is provided above'the cams with an upward extension 33 provided with a screw-driver slot 34. The lower end of the pin 30 may be upset as at 35 to retain it in position and a washer 36 is arranged between the upsetend of the pin and the lower face of the bearing 28.

Each of the lugs r2ts is provided with a radial opening d? in'. which lare slidably to prevent reverse rotation jof said cam member.

6. A device of the character described Comprising a base having a depending portion adapted to be arranged within the filling spout of an automobile radiator and provided with a plurality of radial openings, pins slidably arranged in said openings and a member rotatably carried by said depending portion, said rotatable member being provided With a plurality of cam faces normally arranged between said pins and adapted to engage the latter upon rotation of said rotatable member, one of said pins being provided at its rinner end with a tooth, one of said cam faces being provided with a eoacting tooth adapted to engage the tooth of said pin after said rotatable member has been rotated a suliieient distance to force the outer ends of said pins into 20 engagement with the filling spout.

In testimony whereof I affix my signature.
